• ITMO Researchers Describe Carbon Dot Structure, Discover Red Emission Amplification Method

  Fluorescent carbon nanoparticles, also known as carbon dots, were first described in the early ‘00s. But even today, scientists around the globe still have not reached a consensus on their inner structure and emission process. Carbon dots have a great deal of potential applications due to their biocompatibility with the human body and the ease and low cost of their production as compared to semiconductor quantum dots. Researchers from ITMO University have published two research papers in which they put forth their answers to the burning questions about carbon dots.

• Physicists Proposed Fast Method for Printing Nanolasers From Perovskites

  An international research team has developed a new method of synthesizing miniature light sources. It is based on a special laser which produces millions of nanolasers from a perovskite film in a few minutes. Such lasers look like small disks, work at room temperature and have a tunable emission wavelength from 550 to 800 nm. The high speed and good reproducibility of this method make it promising for the industrial production of single nanolasers as well as whole chains. The study was published in ACS Nano.
